Devexpress如何在ComboBox DataBinding方法中获取索引行？

Question

<dx:GridViewDataComboBoxColumn Caption="<%$Resources: zione%>" Width="15%" Visible="true">                                
    <DataItemTemplate>
        <dx:ASPxComboBox ID="comboZione" 
                      runat="server" 
                      ValueField="TIPB_CTBZIONE"
                      TextField="DEFI_CTBZIONE" 
                      OnDataBinding="comboZione_OnDataBinding" 
                      EnableCallbackMode="false" 
                      OnSelectedIndexChanged="combo_OnSelectedIndexChanged">
        </dx:ASPxComboBox>
    </DataItemTemplate>
</dx:GridViewDataComboBoxColumn>

在代码背后：

protected void comboZione_OnDataBinding(object sender, EventArgs e)
{
    ASPxComboBox cmb = (sender as ASPxComboBox);
    cmb.DataSource = ddlLoadZione(IndexRow);
    // Here I want to bind the different combox on which row, 
    // but I needed a index row to do this. 
}

索引行需要我获得该行的正确值。

Grid.GetRowValues(**IndexRow**, "FieldName")

要完成此任务，我建议您使用The general technique of using the Init/Load event handler文章中描述的方法并设置组合框＆＃39; Init事件处理程序中的DataSource属性。

我相信有可能：

1. 处理ASPxComboBox.Init事件;
2. 根据您的自定义条件（行值等）提供ASPxComboBox.DataSource。
